proc: make the proc_create[_data]() stubs static inlines
Change the proc_create[_data]() stubs which are used when CONFIG_PROC_FS
is not set from #defines to a static inline stubs.
This should fix clang -Werror builds failing due to errors like this:
drivers/platform/x86/thinkpad_acpi.c:918:30: error: unused variable
'dispatch_proc_ops' [-Werror,-Wunused-const-variable]
Fixing this in include/linux/proc_fs.h should ensure that the same issue
is also fixed in any other drivers hitting the same -Werror issue.
[akpm@linux-foundation.org: fix CONFIG_PROC_FS=n]

[akpm@linux-foundation.org: fix build]
